I recently bought a ‘68 Deluxe Reissue from 2104 for a decent price. I also just found 5 NOS Toshiba tubes (12AX7A only at less than 10 bucks a pop).

Is it recommended to change all the appropriate tubes to the NOS, or maybe just V1? Haven’t owned a tube amp for 20 years and re-learning the ins and outs. ChatGPT didn’t recommend it, be he ain’t an expert like you guys. Any thoughts or input would be appreciated. Thank you!!
